Referring to the drawings and rst to Figures 1 to 11, inclusive, the numeral 20 designates a "spring body section, the numeral 2| designates a nom-resilient head section and the numeral y22 designates a non-resilient foot section.

The three sections 20,2! and 22 form a single `'spring lstructure which is adapted to be mounted in a bed'and upon which a mattress not shown'is adapted to be'mounted. l

The body spring structure'ZU comprises an upper rectangular frame member 23, a lower rec- "tan'gular frame member'24 and an intermediate "frame member 25. The spring structure 20 includes a plurality of opposed pairs of helical fsprings 26 and 21, the springs'26 beingformed of "heavier material than the springs 21 and these springs are arranged with their small ends in 'opposed relation.` The springsZ-B which are `out- 'ermost are adapted to be swingably secured 4to the frame member 23 by cutting an-arcuate rec'ess28 in the inner side ofthe frame member 1'23'so that the base convolution 29 of-the'spring 26 may engage within'the recess 28. The Ymaterial forming the frame `member23 is then bent inwardly sufficiently so that the upper convolu- Ation'29 ofthe spring member 26 will be loosely iheld'within the recess28. The inner series of springs 26 aretied together by crossed 'tie bars 3`which are formed at their opposite ends with loops or hooks 3l which engagefabout theupper "-cnvolutions 29 of the springs 26.

A plurality of transversely extendingparallel intermediate frame bars 32 are disposed within the intermediate fra-'me member '25. The frame bar`s32 are disposed in edgewise relation and at ltheir opposite ends the frame members 32 are vvtwisted as at 33 and then extended overl the`intermediate frame member 25. Each frame bar "32 is then `formed with-an--L-shaped extension34 which "is provided lwitha #vertical fouten leg i135.

A spring supporting bracket er arm 36 of L-shape is adjustably secured to the vertical leg 35 by means of a thumb bolt 31. The bracket or hanger member 36 is formed with an outwardly extending upper leg 38 which is adapted to er1- gage over the edge of a bedstead. The bracket member 36 may be formed with an elongated slot 39 through which the thumb bolt 31 engages so that the bracket member 36 may be vertically adjusted in order to adjust the height of the spring member 20 or to adjust the angular relation of the spring member 26 to the horizontal. The transverse tie bars or frame members 32 are formed in their upper edges with al pair of notches 40 within which the apex or lower convolution of the spring 26 is adapted to engage. The bar 32 is also formed with an opening 4I below the upper edge thereof and the free end 42 of the spring 26 is adapted to be threaded into the opening 4|.

A plurality of longitudinally extending tie bars 43 are disposed in parallel relation relative to the sides of the intermediate frame member 25. The tie rods 43 are round in transverse section and are also extended through the openings 4| of the flat transverse tie bars 32. The opposite ends of the longitudinal tie rods 43 may be welded or otherwise xedly secured to the opposite ends of the intermediate frame 25. The bars 32 and rods 43 correlate to form a grid structure or element which is supported by the frame 25.

'Ihe helical springs 21 are disposed in reversed position to springs 26, the lower springs 21 having the lower convolutions 44 thereof secured to the lower frame member 24 in the same manner as the spring convolutions 29 are secured to the upper frame members 23. The lower spring members 21 have their lower convolutions 44 tied together by means of a plurality of crossed tie bars 45. The tie bars 45 are similar to the tie bars 39 and may be formed either from a single piece of material which is stamped out in the form of radially arranged arms having loops at their opposite ends as shown in Figure 9 or the tie bars 45 may be formed in overlapping crossed bars.

The transverse tie bars 32 have formed in their lower edges pairs of notches 46 in which the upper convolution 61 of each coil 21 is adapted to engage. The bars 32 are also formed with an opening 48 through which the end 49 of the spring 21 is adapted to be threaded. As shown in the drawings, the spring structure 26 is adapted to be coated completely with a rubberized coating. The frame structure 23 as shown in Figure is coated with a rubberized coating 50 and the springs 26 are also coated with a rubber or rubberized coating 5|. In like manner the transverse tie bars 32 are coated with a rubber or rubberized coating 52 and the -lower frame structure together with the lower springs and crossed tie bars 45 are adapted to be coated with a rubberized or rubber coating. In this manner, the spring structure will be noiseless and in addition the rubberized coating will prevent corrosion from affecting the metal forming the spring structure.

The bracket or hanger members 36 may also be covered with a rubber or rubberized coating so that these members will not injure the bedstead and in addition in the event there is any movement between the hangers 36 and the bedstead, this movement will be cushioned and the noise of movement will be deadened by the rubber coating on the hangers 36. The head membars 12.

ber 2| comprises a rectangular-shaped frame including an outer frame bar 53, an inner frame bar 54 and side frame bars 55. The frame bars 53, 54 and 55 may be made from a single length of material such as a round bar or the like which may be bent in rectangular form and the ends thereof welded together,

The end members 53 and 54 have secured thereto between the sides 55 a plurality of flat straps 56. The straps 56 are adapted to be extended into openings or channels 51 which are formed in the inner edge portion of the end member 53 and into openings or channels 58 formed in the confronting edge of the rear end member 54. The straps 56 may be welded or otherwise fixed within the recesses 51 and 58. The side frame members 55 have secured thereto in dependent relation a depending arm 59 and an L-shaped bracket member 60 is adjustably secured to the arm 59 'by means of a thumb bolt 6|. The bracket member 6| has formed in the vertical leg 62 thereof an elongated slot 63 through which the bolt 6| engages.

The horizontal leg 64 of the bracket or hanger 66 extends right angularly and outwardly from the vertical leg 62 and is adapted to engage either the upper edge of the bedstead or may engage a ledge or flange formed interiorly of the side boards of the bedstead. The head member 2| is hingedly and detachably secured to the head end of the frame 29 by means of a pair of hinge straps 65. The straps 65 are formed with an arcuate portion 66 engaging about the inner end member 54 of the head frame 2| and the arcuate portion 66 is adapted to be welded or otherwise fixed to the end member 54. Each strap 65 is formed with an arcuate hook 61 which loosely engages about the adjacent end of the frame member 23 so that the head member 2| may be angularly adjusted with respect to the spring structure 20. The frame structure 2| is formed with a rubber coating 68 and in like manner the hinge straps 65 are also formed with a rubber coating 69. The webbing bars or straps 56 may also be coated with a rubber coating and in like manner the depending straps or bars 59 and the bracket member 60 may also be coated with rubber or other yieldable covering.

The foot section 22 is constructed similar to the head section 2| with the exception that the foot section 22 is longer than the head section 2|. The foot section 22 comprises an outer end bar 10, an inner end bar 1| and opposite side The bars 10, 1| and 12 may be formed from a single length of round metal which is adapted to be bent in rectangular shape and the confronting ends thereof welded or otherwise iixed together to form a rectangular foot section. The rectangular frame formed by 'the end members 10 and 1| and side members 12 is provided with a plurality of parallel straps or webbing members 13 which are extended into openings 14 in the end member 10 and are also extended into openings 15 in the end member 1|. The foot section 22 is hingedly secured to the spring structure 2D by means of a pair of hinge straps 16 which are constructed similar to the hinge straps 65. The foot section 22 is adapted to be coated with a rubber coating similar to the spring structure 20 and the head section 2 The foot section 22 on the opposite sides 12 thereof has secured thereto a depending arm 11 to which an L-shaped supporting or bracket member 18 is adapted to be secured by means of a thumb bolt 19. The bracket member 18 is formed with a vertical leg 88 having an elongated slot 8| therein through which the bolt 19 is extended. The horizontal leg 82 of the bracket 18 is lowermost and extends outwardly from the side members |2. The horizontal legs 82 of the 'bracket or supporting members 'i8 are adapted to engage a ledge formed on the side rails of the bedstead or may be engaged with the upper edges of the side rails. By providing an adjustable supporting structure 78 for the foot section 22, the angular relation oi the foot section 22 with respect to the upper surface of the spring section 28 may be easily and quickly adjusted so that this spring structure may be used as a hospital spring where the foot section is raised relative to the intermediate or body section. In like manner the head section 2| may be inclined upwardly for reading or other purposes.

The head section 2| and the foot section 22 are adapted to be disposed in the same plane as the f designated as 83 which in plan is of rectangular conguration substantially the size of the foot section 22. the form of an open basket and comprises an upper rectangular frame 84, a lower rectangular frame 85 and an intermediate rectangular frame 86. A plurality of vertically disposed side bars 81. are secured to the sidemembers of the upper and lower frame members 84 and 85 and a plurality of vertically disposed end connecting bars 88 are connected to the forward and rear portions of the frame members 84 and 85.

The intermediate frame 86 is disposed on the inner sides of the vertical bars 81 and 88 being welded or otherwise fixed thereto. The receptacle 83 is adaptedy to be completely coated with rubber or rubberized material 89 and the receptacle 83 is supported beneath the foot section 22 independently thereof by means of pairsof side supporting or hanger members 90 which extend laterally from the sides of the upper frame member 84. A vertically disposed and downwardly extending bar 9| is formed integral with the horizontal supporting member 9D and the vertical bar 9| is extended as at 92 beneath the bottom of the receptacle 83. In practice the bottom bar 92 is bent in substantially U-form with the bight 92 extending across the bottom of the receptacle 83 and the parallel legs 9| are disposed in the opposite sides of the receptacle 83 and the terminal ends of the legs 9| are bent outwardly as at 90 so as to form receptacle supporting means which are adapted to engage over the upper edge of the side rails of the bedstead.

The spring structure shown in Figures 1 to 11, inclusive, is adapted to be mounted in a conventional bedstead and in normal use the upper The receptacle 83 is constructed inv surface of the spring structurewill be substantially horizontal. The supporting legs 60 for the head section 2| are adjustedk to dispose the head section 2| in a `horizontal position and the supporting legs 18 are also adapted to be adjusted to position the foot section 22 in a horizontal plane. However, in the event the head section 2| has to be raised or inclined to the horizontal for reading or other purposes, the leg member 60 may be lowered so as to extend the foot 64 thereof. This will have the effect of changing the angular relation of the head section 2| relative to the body section 28. If desired the body section 20 may also be inclined to the horizontal by adjusting the leg members 38. Preferably a mattress similar to that shown in Figures 12 to l5 is used in combination with this spring structure so that the lseveral sections of the spring may be adjusted relative to an adjacent section and so that the other side of the spring structure may be cleaned.

The receptacle 83 may be used with the spring structure hereinbefore described and may form a convenient storage space for bed clothes or other articles. Where the spring member 20 is to be used by a relatively heavy person, the heavier springs 28 are disposed in anV uppermost position with the lighter springs 21 lowermost.

'Howeven where a light weight person uses the spring structure, the spring member 20 may be reverted so as to position the lighter springs 21 uppermost. This may be accomplished by unhooking the hinge hooks B5 and 'I6 which are carried by the head and foot sections respectively and then hooking these hooks cntothe lower frame structure 24. The rubber coating which is placed on all the parts of the spring structure hereinbefore described may be placed thereon by either dipping the spring structure in rubber solution or spraying the solution on the spring structure.
